Sonce decoraciones is a feminine singular noun, we must choose the definite article that also matches this form, which is las. On the other hand, tuve comes from the verb tener and is its conjugation for the first person singular in the preterite tense So this tense stands for sentences whose action has been performed at a certain moment in the past. So tuve que translates into I had to.
